When I was a teenager, I wanted to get an Altair 8800 computer, but I couldn’t afford it. Now, I can. But I wanted something smaller, quieter, and about a million times faster. So I made it. I consider this the crowning achievement of my mid-life crisis nostalgia kick.

40 years ago, everyone hated “IBM cards”. I remember folding, spindling, and mutilating them out of spite. Now, they’re an object of nostalgia. When I got my hands on one of the actual printing plates that was used to print the cards, I had to treat it with the respect and dignity it deserved. So …

I wanted to switch to a microcontroller that I could program in C++, prototype with on a breadboard, had every peripheral I would ever need (including USB), would cost less than $10, and would keep working even after I hacked it to pieces. The result is the Black Knight board.
